[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid container constituted by a combination of a container main body, a spout plug mounted on the mouth and neck of the container main body, and an outer lid.

[0002]

2. Description of the Related Art As a container for a liquid such as a toilet bowl cleaning liquid, Japanese Utility Model Laid-Open No. 6-67354 discloses a container body having a cylindrical mouth-neck portion and a spout plug mounted on the mouth-neck portion of the container body. And a container configured with an outer lid. The spout has a base wall and a hollow bulge formed on the upper surface of the base wall. A discharge opening is formed in the base wall. The hollow bulging portion has a tubular wall portion extending from the peripheral edge of the discharge opening formed in the base wall, a top surface wall portion closing the upper surface of the tubular wall portion, and a pouring tubular portion protruding from the tubular wall portion. . The pouring path extending in the pouring tube portion is connected to the inside of the container body through a discharge opening formed in the cylindrical wall portion and the base wall. The spouting cylinder portion extends radially outward and inclines upward, and its tip end surface extends downward and inclines radially outward. A spout is formed on the front end surface of the spout, and an annular seal ridge extending along the periphery of the spout is formed. The outer lid has a cap and a lower engaging portion depending from the cap. On the inner surface of the cap-like portion, a close inner surface having a truncated cone shape is formed, and an annular contact surface is formed. A female screw thread is formed on the inner peripheral surface of the lower engaging portion and is screwed into a male screw thread formed on the outer peripheral surface of the mouth and neck of the container body. When the outer lid is attached to the container body where the mouth and neck is equipped with the spout as required, the cap is covered by the cap-shaped portion of the outer lid, and The female thread is screwed onto the male thread on the mouth and neck. When the outer lid is attached to the mouth-neck of the container body as required, the inner surface of the outer lid is brought into close contact with the annular seal ridge of the spout, thereby sealing the spout of the spout. Moreover, the annular contact surface of the outer lid is brought into contact with the upper surface of the base wall of the spout.

[0003]

Therefore, the above-mentioned actual Kaihei 6
The container of the above-mentioned form disclosed in Japanese Patent No. 67354 has the following problems to be solved.

[0004] close the inner surface which is formed on the cap-shaped portion of the outer lid, an annular sealing protrusion which definitive NOTE decene, opposite the site of the pouring cylinder part of tubular wall portion is formed If the inner surface of the outer lid is firmly brought into close contact with the restraining portion of the cylindrical wall portion due to manufacturing error, etc. The hollow bulging part of the pouring plug is tilted as a whole in the direction in which the tip of the plug displaces downward, and due to this, the annular shape formed on the close inner surface of the outer lid and the tip surface of the pouring tube part. The close contact with the seal ridge is loosened or the two are separated from each other, resulting in insufficient sealing of the spout. Therefore, in the container disclosed in Japanese Utility Model Laid-Open No. 6-67354, in the state where the outer lid is attached to the mouth and neck of the container body as required, the close inner surface of the outer lid is the pouring tube portion. It is closely attached to the annular seal ridge formed on the tip end surface, but between the close inner surface of the outer lid and the portion of the tubular wall portion located on the opposite side of the portion where the spouting tubular portion is formed. Is configured so that there is a slight gap. However,
With this configuration, the hollow bulging portion of the pouring plug is prevented from being entirely inclined in the direction in which the tip of the pouring tube portion is displaced downward. Since the portion of the hollow bulging portion of the pouring plug located on the opposite side of the portion where the pouring cylinder portion is formed is not supported by the outer lid, the hollow bulging portion is rearward, contrary to the above case. There is a tendency to be inclined to. Therefore, the close contact between the inner surface of the outer lid and the annular seal ridge of the pouring plug becomes insufficient, and there is a risk of leakage when a shock or the like is applied to the container.

Further, in the container disclosed in Japanese Utility Model Laid-Open No. 6-67354, the inner surface of the outer lid is still in close contact with the annular seal projection of the pouring stopper due to manufacturing errors and the like. Despite not being pressed, the annular abutment surface of the outer lid is brought into contact with the upper surface of the base wall of the spout to prevent downward movement of the outer lid, thus forming the spout There is a risk that the existing spout will not be sufficiently sealed. If the formation of the annular abutment surface is omitted in order to solve such a problem, a female thread formed on the lower engaging portion of the outer lid and a male thread formed on the mouth-neck portion of the container body. Are excessively screwed together, resulting in an undesired deformation of the outer lid and / or the spout, or impairing the sealing of the spout formed in the spout, as well as the neck of the container body. There is a possibility that the torque required to detach the outer lid body from the motor becomes excessive.

The present invention has been made in view of the above facts, and its first technical problem is to improve the above-mentioned conventional liquid container so that the hollow bulging portion of the pouring plug is inclined. Is reliably prevented, and the inner surface of the outer lid is firmly brought into close contact with the annular seal projection of the spout to ensure that the spout is sufficiently well sealed.

A second technical object of the present invention is to improve the above-mentioned conventional liquid container so that the close inner surface of the outer lid body is surely brought into close contact with the annular seal ridge of the spout plug to spout the spout. Is ensured to be sufficiently well sealed, and excessive engagement of the outer lid with the mouth / neck portion of the container body is reliably prevented.

A large number of concavo-convex portions 62 extending vertically are formed on the outer peripheral surface of the outer peripheral surface of the outer peripheral surface of the outer peripheral surface so as to prevent the fingers from slipping.

As shown in FIGS. 5 and 6, the spout 4 is mounted on the neck 8 of the container body 2. Base wall 1 of spout 4
The outer hanging wall 16 formed on the lower surface of the
The annular locking ridge 20 formed on the outer hanging wall 16 is locked to the annular locking ridge 10 formed on the mouth / neck portion 8, and thus the pouring plug 4 is It is locked to the neck 8 of the container body 2. An inner hanging wall 18 formed on the lower surface of the base wall 14 of the spout 4 is inserted into the mouth / neck portion 8. The base wall 14 of the spout 4 is located on the upper surface of the mouth / neck portion 8. Since the lower surface of the base wall 14 is brought into close contact with the upper surface of the mouth / neck portion 8 and the outer peripheral surface of the upper half of the inner hanging wall 18 is brought into close contact with the inner peripheral surface of the mouth / neck portion 8, the mouth / neck portion 8 The gap with the tap 4 is sealed.
As can be clearly understood from FIGS. 5 and 6, the spout passage 36 formed in the spout tube portion 30 of the spout 4 has the tubular wall portion 2
8 and the discharge opening 24 formed in the base wall 14
It is communicated with the inside of the container body 2 via. Therefore, with the outer lid 6 not attached to the mouth / neck portion 8,
For example, when the main body of the container main body 2 is compressed while the container main body 2 is set upside down, the liquid contained in the container main body 2 causes the liquid contained in the container main body 2 to be discharged into the discharge opening 24, the cylindrical wall portion 28, and the pouring wall 4. It is poured out from the outlet 38 through the outlet 36.

An outer lid 6 is attached to the mouth / neck portion 8 to which the spout 4 is attached, and a cap-like portion 50 of the outer lid 6 covers the spout 4 and an engaging lower portion of the outer lid 6 52 is engaged with the outer peripheral surface of the mouth / neck portion 8. An outer lid 6 is provided on the mouth / neck portion 8 of the container body 2.
When attaching, the outer lid 6 is fitted on the mouth / neck portion 8 to which the pouring plug 4 is attached, and the outer lid 6 is rotated clockwise as viewed from above in FIG. Thus, the male thread 12 formed on the outer peripheral surface of the mouth / neck portion 8 is screwed into the female thread 60 formed on the inner peripheral surface of the engaging lower portion 52 of the outer lid body 6, and thus the outer side. The lid 6 is moved downward with rotation. Then, when the outer lid body 6 is moved to the position shown in FIG. 5, the close contact inner surface 58 formed on the cap-shaped portion 50 of the outer lid body 6 causes the annular seal projection 40 and The restraint ridge 44 is brought into contact with the restraint ridge 44. The abutment of the intimate inner surface 58 against the annular sealing ridge 40 and the restraining ridge 44 is preferably set to be realized substantially simultaneously. The contact of the close contact inner surface 58 with the annular seal projection 40 is sufficiently uniform over the entire circumference of the annular seal projection 40, and the contact of the close contact inner surface 58 with the restraining projection 44 is substantially the entire length of the restricting projection 44. The virtual surface defined by the tip of the annular seal ridge 40 and the virtual surface defined by the tip of the restraining ridge 44 are in close contact with each other so as to be sufficiently uniform across a part of a truncated cone shape corresponding to the inner surface 58. It is desirable to be able to

On the other hand, as clearly shown in FIG. 5, when the close inner surface 58 of the cap 50 of the outer lid 6 is brought into contact with the annular seal projection 40 and the restraining projection 44 of the spout plug 4. It is important that there is a gap G between the upper surface of the base wall 14 of the spout 4 and the annular contact projection 56 formed on the cap-shaped portion 50 of the outer lid 6. The gap G is 0.
It is preferably 1 to 1.0 mm, particularly 0.3 to 0.6 mm.

When the outer lid 6 is further rotated clockwise as viewed from above in FIGS. 5 and 6 and moved downward with the rotation, the cap of the outer lid 6 is clearly shown in FIG. The close inner surface 58 of the groove 50 is pressed against the seal ridge 40 and the restraint ridge 44 of the pouring plug 4 to be brought into close contact with each other, and the annular seal ridge 40 and the restraint ridge 44 are somewhat elastically compressed by such close contact. It can be transformed. On the left side of the spout 4 in FIG. 6, the inner surface 58 of the outer lid 6 is closely contacted.
Is closely contacted with the annular seal ridge 40, and the close inner surface 58 of the outer lid body 6 is closely contacted with the restraining ridge 44 on the right side of the spout 4 in FIG. Therefore, a force is applied to the hollow bulging portion 26 of the pouring plug 4 from the left side and the right side in a balanced manner, and the hollow bulging portion 26 does not have an undesired inclination. Then, the close inner surface 58 of the outer lid 6 is brought into close contact with the annular seal ridge 40, whereby the spout 38 of the spout 4 is sufficiently and reliably sealed. Even if there is some error in the molding of any one of the annular seal ridge 40, the restraint ridge 44, and the close inner surface 58 of the outer lid body 6, the annular seal ridge 40 and / or the restraint ridge 44 is elastically compressed. The deformation appropriately compensates for such an error.

As shown in FIG. 6, when the close inner surface 58 of the cap-like portion 50 of the outer lid 6 is brought into close contact with the annular seal ridge 40 and the restraining ridge 44 of the spout 4, the outer lid is closed. The annular contact projection 56 of the body 6 is brought into contact with the upper surface of the base wall 14 of the spout plug 4. When the outer lid body 6 is further rotated clockwise as viewed from above in FIG. 6 and is further moved downward, the contact protrusions 56 of the outer lid body 6 are placed on the upper surface of the base wall 14 of the spout plug 4. It is pressed into contact, which prevents the outer lid 6 from moving further downward, thus ensuring that the female thread 60 of the outer lid 6 is over-threaded onto the male thread 12 of the mouth / neck 8. To be prevented.

[0026]

According to one aspect of the present invention, the hollow bulging portion of the pouring plug is sufficiently prevented from being tilted, and the close inner surface of the outer lid body serves as the annular sealing ridge of the pouring plug. Enough close enough to ensure the spout is sealed.

Further, according to one aspect and another aspect of the present invention, the close inner surface of the outer lid is surely brought into close contact with the annular seal ridge of the spout plug, and the spout is sufficiently well sealed. Therefore, it is possible to reliably prevent the outer lid from being excessively engaged with the mouth / neck portion of the container body.
